Victor Martinez and James McCann also drove in runs for the Tigers. Detroit pulled within 5 1/2 games of idle AL Central-leading Cleveland.

Verlander (10-6) allowed one run and five hits and struck out five to pick up the victory. He is 3-0 in his last five starts.

Francisco Rodriguez earned his 28th save.

Pomeranz (8-8), recently acquired from the San Diego Padres, gave up four hits and struck out seven in six innings. Both of the runs he allowed came via Iglesias’ homer.

Boston failed to homer Monday, ending a streak of 15 straight games with at least one.

Pomeranz entered Monday’s start looking to bounce back from his dismal Boston debut last week against San Francisco, in which he gave up five runs in just three innings.

He was cruising through five innings Monday, allowing just two hits. That changed in the sixth when Iglesias crushed Pomeranz’s fastball high over the Green Monster in left for a two-run homer to put the Tigers up 2-1.

Iglesias scored his second run of the game in the eighth, trotting across home plate on Martinez’s single off reliever Clay Buchholz to make it 4-1.

Boston loaded the bases on three straight singles off Justin Wilson to begin its half of the eighth. A single by Sandy Leon pulled the Red Sox within 4-2, but Wilson settled down to get an out and Rodriguez came on to help end the rally.

Boston’s hitters had several long at-bats against Verlander, pushing his pitch count above 40 through just two innings. In the second, Travis Shaw lined a double into the right-field corner, scoring Jackie Bradley Jr.
